The Wall Street Journal is reporting investigators have found concrete evidence on computers used by Army intelligence analyst Bradley Manning that link him with the leak of more than 90,000 classified Afghanistan war reports. On Thursday, the Army said Manning had been transferred from a base in Kuwait to a Marine Corps brig in Quantico, Virginia. Manning was charged earlier this month by the military with illegally taking secret State Department files and leaking a classified video that showed a US military helicopter killing a group of people in Baghdad including two Reuters journalists.
